Carl Chambers Rallye

[Niall]

I'm sure if you went to a motor heritage museum and it was full of battered up old cars, you would ask for your money back I know 99% of any other visitors would...

This. When you consider how many 306s were built, 1 not being driven is not a massive deal. There's probably been more than that written off as damaged stock before they even touched the Tarmac!
IMO there is nothing wrong with keeping 1 mint for future generations to see how we used to do things.
Not only that, it's probably a investment to Carl. How much is that going to be worth to a motor museum in 15-20 years? A lot I would imagine
